(4) Multi-plane non-matrix PWB
(set as “Non-matrix circuit” on the “Basic setting” screen)
The angle of each circuit is different from each other and the distance (pitch) between circuits is
not equal on this type of PWB.
Specify “X,” “Y” and “Angle” of each circuit on the “Circuit Layout” screen (see Section 4.3.3.4
“Circuit Layout”) to arrange circuits on a board.
Therefore, even though the pitch between two consecutive circuits is different from the other one
and/or the angle of one circuit is different from that of another one, the system can handle them
respectively.
If you specify the same circuit pitch and the same angle, you can create PWB data for a
multi-plane matrix PWB also.
1) PWB dimensions:
Enter the dimensions of the PWB including all circuits.
2) PWB layout offset:
Enter the length from the PWB position reference to the PWB layout end point in the same
way as a single-circuit PWB.
3) PWB configuration:
Select the <Non-matrix circuit> button.
4) BOC type:
◆ Not Used: Select this button when any BOC mark is not used.
◆ PWB marks: Select this button to use BOC marks on a board to correct the
component placement coordinates.
◆ Circuit marks: Select this button to recognize BOC marks of each circuit on a
multi-plane (circuit) board to correct component placement coordinates.
If there are many circuits on a board, this selection requires much time
to recognize marks, but the accuracy of component placement tends to
be higher than that when you select the <PWB marks> button.

5) Circuit dimensions:
Enter the dimensions of a circuit (the dimensions that include all placement coordinates).
Example)
6) Circuit layout offset:
Enter the distance from the circuit origin of the reference circuit to the left bottom corner (this
is an always fixed point regardless of the board transport direction) of the reference circuit.
7) First circuit position
8) Circuit divide No
9) Circuit pitch
You do not have to set these items for a multi-plane non-matrix board (these items are
disabled).
10) PWB height
11) PWB thickness
12) Back height
13) Clamp offset
Enter these fields in the same manner as those for a single- circuit PWB.
14) Global Bad Mark
Enter the coordinates of a position of a global bad mark viewed from the board reference
position.
When you select the <Not Used> button, “***” is displayed in the “X” and “Y” coordinate input
fields.
The maximum number of circuits the system can create on a multi-plane
non-matrix board is shown below.
When a standard bad mark is used: 1,200 circuits
When an extended bad mark is used: 1,200 circuits

15) Bad mark:
Select the <Not Used> button or the <Used> button depending on whether a bad mark is
used or not. When you select the <Not Used> button, “***” appears in the “X” field and the
“Y” field respectively. When you select the <Used> button, enter the distance from the
circuit origin (circuit reference position) to the center of a bad mark.
* In the above case, enter X = a and Y = b.
<Usage of a bad mark and the operation flow>
i) Enter coordinates of a bad mark into PWB data (that is, to the “Bad mark position”
fields.)
ii) Before feeding a PWB, affix a bad mark at the spot specified with the bad mark
coordinates on a defective circuit.
iii) Before the start of production, the OCC or bad mark sensor reads a bad mark of
each circuit. When a bad mark is recognized, components are not placed on the
corresponding circuit.
The requirements for a bad mark: the mark must be distinct in the color
from a PWB, and its diameter must be 2.5 mm or greater. If a bad mark is
used, the production time will be longer by the mark recognition time.
* For the extended bad mark, refer to "4.3.3.5 Extended bad mark."
* If the bad mark is set out of the circuit, use an extension bad mark.
